Provide Runtal ThermoTouch radiation of the lengths and in locations as indicated, and of capacities, style and having accessories as scheduled. The ThermoTouch radiation shall be of one-piece all-welded steel construction, consisting of active flattened hot water heating tubes welded to headers at each end, plus a front set of inactive tubes for added thermal protection, with a total depth of no more than 2-3/4”. The ThermoTouch radiator shall include an integral heavy gauge (0.09” minimum) all-welded perforated flat top grille which covers the entire radiator from the front inactive tubes to within ¼” of the wall.

ThermoTouch models to have steel corrugated fins welded to both sides of the active water tubes to increase the convective output of the unit. There shall be no less than 32 fins per foot. Fins shall start within 1” of the headers, and shall be spot-welded three times per tube.

The headers shall include all necessary inlet, outlet and vent connections as required. Standard connection sizes are ½” NPT tapered thread for supply and return piping, and 1/8” for the vent connection. Internal baffling is provided where required for proper water flow.

ThermoTouch panels shall be available in lengths from 2’-0” to 29’-6” in six inch increments without the need for splicing. The panel radiation shall be capable of being mounted to typical stud wall construction without additional blocking or strapping. Appropriate wall mounting brackets shall be provided with the radiation.

Pressure Ratings:

Pressure ratings for the radiation shall be as follows:

STANDARD: Working pressure-56 PSI maximum, Test Pressure-74 PSI maximum
OR
MEDIUM: Working pressure-85 PSI maximum, Test Pressure-110 PSI maximum
OR
HIGH: Working pressure-128 PSI maximum, Test Pressure 184 PSI maximum

ThermoTouch expansion shall not exceed 1/64” per foot of radiation at 215ºF. The installer shall provide adequate expansion compensation for each radiator.

ThermoTouch radiation shall be cleaned and phosphatized in preparation for the powder coat finish. The radiation is then finish painted with a gloss powder coat finish, for a total paint thickness of 2-3 mils (0.002” - 0.003”).
